Simultaneous measurement of force and displacement signal
The force operating on the sample is generated electromagnetically in the TMA 402 Hyperion®. This guarantees a quick response time for experiments with a changing load, e.g. tests on creep behavior. A highly sensitive force sensor (digital resolution < 0.01 mN) continuously measures the force exerted via the push rod and readjusts it automatically. This sets the TMA 402 Hyperion® apart from other instruments, which use only preset values.
Vacuum-tight thermostatic measuring system
The entire TMA 402 F1/F3 Hyperion® measuring system is thermally stabilized via water-cooling. This ensures that the measurement will not be influenced by heat from the furnace or by temperature fluctuations in the local environment. All joints have a vacuum-tight design to allow measurements in a highly pure atmosphere or under vacuum. Pressures of less than 10-4 mbar can be achieved in the TMA 402 F1/F3 Hyperion® with the use of a turbo molecular pump. In combination with the integrated mass flow controllers (MFC) for purge and protective gases (optional in the TMA 402 F3 Hyperion®), measurements in highly pure inert gas or in oxidizing atmospheres can be optimally controlled
Precise force control
The electronic control system for the TMA 402 Hyperion® allows forces to be set in the mN-range. This enables testing even on sensitive materials such as thin fibers or films. The force operating on the sample can be altered via the software in a stepwise or linear fashion. This makes it particularly simple to carry out such analyses as creep or stress sweep tests. The premium version of the TMA 402 Hyperion®, the TMA 402 F1 Hyperion®, provides even more capabilities. From single pulse in rectangular or ramp form to continuous modulation with a freely selectable frequency (up to 1 Hz), every possibility is covered. This model is particularly well-suited for determining visco-elastic material properties such as elasticity and creep modulus.

The modular design of the TMA 402 Hyperion® makes it unique among the competition
To adjust the instrument for the respective temperature ranges, all that needs to be done is to exchange the furnace. This can be done by the operator. If using the optional double furnace hoist, switching to a second furnace takes only moments.
Sample holder systems tailored to the task
Depending upon the question at hand and the geometry of the sample, the operator has a variety of sample holders to choose from. Holding devices for expansion, penetration, and tension measurements are available, as well as push rods and supports for analyses in 3-point bending. Accessories for the temperature range up to 1000°C are made of fused silica. For the high temperature range, aluminum oxide varieties are available.
In the TMA 402 Hyperion®, the thermocouple can be changed quickly and easily. Besides Type K, the S and E varieties are also available. The system electronics recognize the installed sensor automatically.
Special sample holders
With the help of special sample containers, the expansion behavior of powders, pastes and liquids can be analyzed, as can metals all the way to the melting point. Accessories for experiments on swelling behavior upon immersion are also available.
Measurements in humid atmospheres
The copper furnace for the TMA 402 Hyperion® instruments can be used as a conventional furnace in the temperature range from -150°C to 500°C. The furnace type was especially conceived for measurements in humid atmospheres and can be coupled to the humidity generator via a special inlet adapter. The humidified gas arrives at the sample from above in this case, and a special gas duct effectively prevents the protective gas from thinning the water concentration unwantedly. The operation in humid atmosphere is possible in the temperature range from 0°C to 100°C.
